About the Magician
I'm not sure how well Tarot Cards yield up their secrets when considered in isolation. A Tarot reading is a dynamic event: the meaning of each card depends upon, and is modified by, each of the other cards in the spread.
Having said which, each card has, of course, its own intrinsic meaning, without which we wouldn't be able to see how it influences any of the others!
If other cards in the spread suggest negativity, then the Magician is a trickster; if he represents a person in the reading, then that person is not to be trusted, but will be duplicit and two-faced. If he represents an event, then be careful! Nothing is quite what it seems. In business there may be fraud; or at least some shady dealings. In love, the magician is not to be trusted, even when found with good cards. There is too much of Mercury in him. If he shows up with the Devil, in a query about a relationship, don't trust a word he says. He will lie, and amuse himself as he does so.
With positive cards, the Magician is a completely different character. Charming, ingenious, and inventive. He's the go-to man, the trouble shooter who sees a way straight through the problem. A great communicator, he will talk himself out of situations which looked hopeless with ease. He is an initiator, and an ideas man. He gets the ball rolling. He is fast thinking, smooth talking and always charming. Some people instinctively mistrust him and perhaps with good reason; he can be just a little bit to clever for his own good.
With the magician, the chances are that something new is round the corner - but its unlikely to be quite what you had planned. Expect the unexpected - he's always got another trick up his sleeve!
